Summary:
The L17 protein is a component of the 50S subunit of the ribosome.

L17 interacts directly with tRNA [Metspalu81] and can be crosslinked to 23S rRNA [Osswald90]. L17 can also be crosslinked to the spiramycin derivative dihydrospiramycin and may thus be located near the peptidyl transferase center [Bischof95].

Summary:
The ribosome is a complex machinery that translates the genetic code.

A crystal structure of the E. coli ribosome has been determined at 3.5 Å resolution [Schuwirth05]. Additional crystal structures of the ribosome with tRNA bound in two functionally distinct states reveal how a ratchet-like motion of the small and large subunits contributes to translocation, termination of translation, and ribosome recycling [Zhang09, Dunkle11].

Approximately eight molecules of Zn2+ are bound to the ribosome; therefore, it appears that a large fraction of intracellular Zn2+ is ribosome-associated [Hensley11].
